FIG. 1A is a schematic diagram of an exemplary application scenario of an exemplary execution status indicating method according to various disclosed embodiments of the present disclosure. As shown in FIG. 1A, the application scenario includes an unmanned aerial vehicle (UAV) and a remote controller. The remote controller may be configured to send control instructions to the UAV, e.g., to send control instructions to the UAV via keys on the remote controller. The UAV may be configured to receive control instructions from the remote controller, and to perform operations according to the control instructions. In the descriptions of some embodiments, a UAV is taken as an example merely for illustrative purposes, which is not intended to limit the scope of the present disclosure. In the present disclosure, the UAV can be replaced with an unmanned vehicle, or an unmanned boat, or the like, according to various application scenarios.

FIG. 1B is a schematic diagram of another exemplary application scenario of an exemplary execution status indicating method according to various disclosed embodiments of the present disclosure. As shown in FIG. 1B, the application scenario includes a UAV and a smart device. The smart device may be configured to send control instructions to the UAV, e.g., to send control instructions to the UAV through an application (APP) on the smart device. The UAV may be configured to receive control instructions from the smart device, and to perform operations according to the control instructions.

FIG. 1C is a schematic diagram of another exemplary application scenario of an exemplary execution status indicating method according to various disclosed embodiments of the present disclosure. As shown in FIG. 1C, the application scenario includes a UAV, a remote controller, and a smart device. The remote controller can communicate with the UAV and the smart device. In some embodiments, control instructions can be sent from the remote controller to the UAV. In some other embodiments, control instructions can be sent from the smart device to the remote controller, and then sent from the remote controller to the UAV. The UAV can receive the control instructions sent from the smart device or the remote controller, and perform operations according to the control instructions.

In some embodiments, the UAV performing operations according to the control instructions may include the UAV controlling itself according to the control instructions, e.g., controlling a flight mode of the UAV or the like, and/or may include the UAV controlling a load carried by the UAV according to the control instructions.

FIG. 2 is a flowchart of an exemplary execution status indicating method according to various disclosed embodiments of the present disclosure. With reference to in FIG. 2, the method is described below.

At 201, the UAV receives control instructions sent from a control device, where the control instructions are configured to control a controlled object.

In some embodiments, the controlled object may include a load carried by the UAV. In some other embodiments, the controlled object may include the UAV. In the embodiments that the controlled object includes the UAV, the control instructions may be configured to switch a flight mode of the controlled object. The flight mode may include, for example, a P-mode that uses a global positioning system (GPS) receiver or a visual positioning system to achieve precise hover of the UAV, or an A-mode that provides attitude stabilization without using the GPS receiver or the visual positioning system for positioning, or an F-mode as an auxiliary function mode.

In some embodiments, the load may include, for example, a camera, a robot arm, a detection instrument, or the like.

At 202, the UAV is controlled to display an execution status of the control instructions executed by the controlled object.

In some embodiments, the UAV may be controlled to display the execution status of the control instructions executed by the controlled object, such that the operator can observe, e.g., watch, the UAV to determine the execution status of the control instructions executed by the controlled object. As such, time for the operator to observe the indicator light on the remote controller or the APP may be reduced, as compared to the cases that the operator needs to observe the indicator light on the remote controller or the APP to determine the execution status of the control instructions executed by the controlled object. Accordingly, distraction of the operator's attention from observing the UAV caused by a need for the operator to constantly observe the indicator light on the remote controller or the APP may be suppressed. A potential safety hazard for the UAV operation may be suppressed.

Another exemplary execution status indicating method is provided. In some embodiments, based on above-described example(s) of execution status indicating method, an executing entity for process 201 may include a wireless receiver of the UAV, e.g., a wireless fidelity (WIFI) apparatus or a high-definition image transmission apparatus such as a Lightbridge 2 (LB2) apparatus. An executing entity of process 202 may include a main controller of the UAV.

In some embodiments, process 202 may include controlling an indicator light at the UAV to indicate an execution status of the control instructions executed by the controlled object.

An indicator light provided at a conventional UAV indicates only an operation status of the UAV itself, e.g., a UAV alarm status for a low battery level, a nose position of the UAV, a tail position of the UAV, or the like. In the present disclosure, the indicator light provided at the UAV may be controlled to display an execution status of the control instruction executed by the controlled object.

In some other embodiments, process 202 may include controlling an attitude of the UAV to indicate an execution status of the control instructions executed by the controlled object. In some embodiments the attitude of the UAV may include an overall flight attitude of the UAV or an action attitude of a movable component of the UAV. For example, the overall flight attitude of the UAV may be controlled to indicate an execution status of the control instructions executed by the controlled object, or the action attitude of the movable component of the UAV may be controlled to indicate an execution status of the control instructions executed by the controlled object. The overall flight attitude of the UAV may include, for example, leveling, climbing, gliding, turning, rolling, pitching, or the like. The action attitude of the movable component of the UAV may include, for example, a deformation of a supporting arm, etc.

In some embodiments, an indicator light at the UAV or an attitude of the UAV may be controlled to display an execution status of the control instructions executed by the controlled object, such that the operator may observe the UAV to determine the execution status of the control instructions executed by the controlled object. In the present disclosure, time for the operator to observe the indicator light on the remote controller or the APP may be reduced, and operation safety of the UAV may be improved.

FIG. 3 is a flowchart of another exemplary execution status indicating method according to various disclosed embodiments of the present disclosure. The method shown in FIG. 3 is similar to that described above in connection with FIG. 2. In the embodiments shown in FIG. 3, for example, the controlled object may include a photographing apparatus, and the indicator light may be used to indicate an execution status of the control instructions executed by the controlled object for illustrative purposes. In these embodiments, as shown in FIG. 3, the method includes processes described below.

At 301, the UAV receives control instructions sent from a control device, where the control instructions are configured to instruct the photographing apparatus to perform an image capturing operation.

In some embodiments, the control device may include, for example, at least one of a remote controller, a smart device communicating with the remote controller, or a smart device communicating with the UAV.

At 302, an indicator light at the UAV is controlled to indicate an execution status of the control instructions executed by the photographing apparatus.

In some embodiments, the indicator light at the UAV may be controlled to indicate the execution status of the control instructions executed by the photographing apparatus, such that the operator can observe the UAV to determine the execution status of the control instructions executed by the photographing apparatus. Thus, time for the operator to observe the indicator light on the remote controller or the APP may be reduced, as compared to the cases that the operator needs to observe an indicator light at a remote controller or an APP to determine an execution status of control instructions executed by a photographing apparatus. Accordingly, distraction of the operator's attention from observing the UAV caused by a need for the operator to constantly observe the indicator light on the remote controller or the APP may be suppressed. A potential safety hazard for the UAV operation may be suppressed.

Another exemplary execution status indicating method is provided. In some embodiments, based on above-described examples of execution status indicating method, the executing entity for process 301 may include a wireless receiver of the UAV. The executing entity for process 302 may include a main controller of the UAV.

In some embodiments, process 302 may include controlling a color of the indicator light and/or a blinking frequency of the indicator light to indicate an execution status of the control instructions executed by the photographing apparatus.

In some embodiments, the execution status of the control instructions executed by the photographing apparatus may include an operation status of the photographing apparatus after the photographing apparatus executes the control instructions, e.g., taking videos, taking photos, or the like. Further, the execution status of the control instructions executed by the photographing apparatus may include whether the photographing apparatus successfully executes the control instructions. If the photographing apparatus successfully executes the control instructions, the operation status of the photographing apparatus after the photographing apparatus executes the control instructions may include an operation status of the photographing apparatus after the photographing apparatus successfully executes the control instructions. If the photographing apparatus fails to execute the control instructions, the operation status of the photographing apparatus after the photographing apparatus executes the control instructions may include an operation status of the photographing apparatus after the photographing apparatus fails to execute the control instructions. Further, the execution status of the control instructions executed by the photographing apparatus may include the control instructions being successfully received.

In some embodiments, the photographing apparatus may include a camera. Correspondingly, the control instructions in process 301 may be configured to instruct the camera to perform an image capturing operation. Further, the photographing apparatus may also include a gimbal for securely supporting the camera. Correspondingly, the control instructions may be configured to instruct a mode of the gimbal, also referred to as a “gimbal mode,” such as, for example, a free mode, a yaw following mode, a locking mode, or the like.

If the image capturing operation of the camera is successfully executed, the color and/or the blinking frequency of the indicator light may be controlled, and controlling the color and/or the blinking frequency of the indicator light may include controlling the indicator light to emit light of a first color and/or controlling the indicator light to blink at a first frequency. For example, the indicator light may be controlled to emit green light and blink for several times. In some embodiments, controlling the indicator light to emit light of the first color and/or controlling the indicator light to blink at the first frequency may be used to indicate that the camera successfully executes the control instructions.

In some embodiments, controlling the overall flight attitude of the UAV to indicate the execution status of the control instructions executed by the camera may include, for example, the UAV performing a small-range pitching, which is similar to human nodding, to indicate that the camera successfully executes the control instructions. Controlling the attitude of the movable component of the UAV to indicate the execution status of the control instructions executed by the camera may include, for example, using a first attitude of a support frame after being deformed to indicate that the camera successfully executes the control instructions.

In some embodiments, after controlling the indicator light to emit light of the first color and/or controlling the indicator light to blink at the first frequency, the method may further include controlling the indicator light to emit light of a second color and/or controlling the indicator light to blink at a second frequency. In some embodiments, operation statuses of the camera after the camera successfully executes the control instructions may correspond to colors and/or frequencies in a one-to-one manner. That is, one operation status of the camera may correspond to one color and/or one frequency of the indicator light. For example, when the camera is at a video recording status, the indicator light may be controlled to slowly blink in red. When the camera is at a photo taking status, the indicator light may be controlled to rapidly blink in red. In some embodiments, controlling the indicator light to emit light of the second color and/or controlling the indicator light to blink at the second frequency may be used to indicate an operation status of the camera after the camera successfully executes the control instructions.

In some embodiments, controlling the overall flight attitude of the UAV to indicate the execution status of the control instructions executed by the camera may include using a selected overall flight attitude of the UAV to indicate an operation status of the camera after the camera successfully executes the control instructions. Operation statuses of the camera after the camera successfully executes the control instructions may correspond to selected overall flight attitudes in a one-to-one manner. In some embodiments, controlling the action attitude of the movable component of the UAV to indicate the execution status of the control instructions executed by the camera may include using a selected action attitude of the movable component of the UAV to indicate an operation status of the camera after the camera successfully executes the control instructions. Operation statuses of the camera after the camera successfully executes the control instructions may correspond to selected action attitudes in a one-to-one manner.

If the image capturing operation of the camera is unsuccessfully executed, the color and/or the blinking frequency of the indicator light may be controlled, and controlling the color and/or the blinking frequency of the indicator light may include controlling the indicator light to emit light of a third color and/or controlling the indicator light to blink at a third frequency. For example, the indicator light may be controlled to rapidly blink in red for several times. In some embodiments, controlling the indicator light to emit light of the third color and/or controlling the indicator light to blink at the third frequency may be used to indicate that the camera fails to execute the control instructions.

In some embodiments, controlling the overall flight attitude of the UAV to indicate the execution status of the control instructions executed by the camera may include, for example, the UAV performing a small-range left-right swinging, which is similar to human shaking head, to indicate that the camera fails to execute the control instructions. In some embodiments, controlling the action attitude of the movable component of the UAV to indicate the execution status of the control instructions executed by the camera may include, for example, using a second attitude of the support frame after being deformed to indicate that the camera fails to execute the control instructions.

In some embodiments, the photographing apparatus further includes a gimbal and the UAV includes a first indicator light and a second indicator light. The second indicator light of the UAV may be controlled to indicate an execution status of the gimbal, and the first indicator light of the UAV may be controlled to indicate an execution status of the camera. Controlling the color and/or the blinking frequency of the indicator light may further include controlling the indicator light, e.g., the second indicator light, to emit light of a fourth color and/or controlling the indicator light, e.g., the second indicator light, to blink at a fourth frequency. Operation statuses of the gimbal after the gimbal executes the control instructions, e.g., an operation status of the free mode, an operation status of the yaw following mode, or an operation status of the locking mode, may correspond to colors and/or frequencies in one-to-one manner. In some embodiments, controlling the indicator light, e.g., the second indicator light, to display the fourth color and/or controlling the indicator light, e.g., the second indicator light, to blink at the fourth frequency may be used to indicate an operation status of the gimbal after the gimbal executes, successfully or unsuccessfully, the control instructions. For example, when the gimbal is in the free mode, the indicator light, e.g., the second indicator light, of the UAV may be controlled to slowly blink in yellow. When the gimbal is in the yaw following mode, the indicator light, e.g., the second indicator light, of the UAV may be controlled to rapidly blink in yellow. When the gimbal is in the locking mode, the indicator light, e.g., the second indicator light, of the UAV may be controlled to continuously emit yellow light.

Similar to the situation for the camera, for the gimbal, not only the indicator light of the UAV may be controlled to indicate success or failure of the gimbal executing the control instructions, but also the attitude of the UAV may be controlled to indicate an execution status of the control instructions executed by the gimbal, e.g. an operation status of the gimbal after the gimbal executes the control instructions or whether the gimbal successfully executes the control instructions. Reference can be made to descriptions for the camera, which are not repeated here. Controlling the attitude of the UAV to indicate an execution status of the control instructions executed by the camera and an execution status of the control instructions executed by gimbal may include controlling the attitude of the UAV to indicate an execution status of the control instructions executed by the gimbal, and then controlling the attitude of the UAV to indicate an execution status of the control instructions executed by camera.

Further, after process 302 is performed, the method may also include controlling the indicator light at the UAV to switch from indicating the execution status of the control instructions executed by the photographing apparatus to indicating the operation status of the UAV. For example, at process 302, an indicator light at the UAV for indicating a tail position of the UAV may be controlled to indicate the execution status of the control instructions executed by the photographing apparatus; and after process 302, the indicator light may be switched to indicate the tail position of the UAV.

In some embodiments, the color and/or the blinking frequency of the indicator light at the UAV may be controlled to indicate the execution status of the control instructions executed by the photographing apparatus, such that the operator can observe the UAV to determine the execution status of the control instructions executed by the photographing apparatus. Accordingly, time for the operator to observe the indicator light at a remote controller or an APP may be reduced. Distraction of the operator's attention from observing the UAV caused by a need for the operator to constantly observe the indicator light on the remote controller or the APP may be suppressed. A potential safety hazard for the UAV operation may be suppressed.

FIG. 4 is a flowchart of another exemplary execution status indicating method according to various disclosed embodiments of the present disclosure. The method shown in FIG. 4 is similar to that described above in connection with FIG. 2. In the embodiments shown in FIG. 3, for example, the controlled object may include a UAV, and the indicator light may be controlled to indicate an execution status of the control instructions executed by the UAV for illustrative purposes. As shown in FIG. 4, the method includes processes described below.

At 401, the UAV receives control instructions sent from a control device, where the control instructions are configured to instruct the UAV to switch the flight mode of the UAV.

In some embodiments, the control device may include, for example, at least one of a remote controller, a smart device communicating with the remote controller, or a smart device communicating with the UAV.

At 402, an indicator light at the UAV is controlled to indicate an execution status of the control instructions executed by the UAV.

In some embodiments, the indicator light at the UAV may be controlled to indicate an execution status of the control instructions executed by the UAV, such that the operator can observe the UAV to determine the execution status of the control instructions executed by the UAV. Thus, time for the operator to observe the indicator light on the remote controller or the APP may be reduced, as compared to the cases that the operator needs to observe the indicator light on the remote controller or the APP to determine the execution status of the control instructions executed by the UAV. Accordingly, distraction of the operator's attention from observing the UAV caused by a need for the operator to constantly observe the indicator light on the remote controller or the APP may be suppressed. A potential safety hazard for the UAV operation may be suppressed.

Another exemplary execution status indicating method is provided. In some embodiments, based on above-described examples of execution status indicating method, an executing entity for process 401 may include a wireless receiver of the UAV, e.g., a wireless fidelity (WIFI) apparatus or a high-definition image transmission apparatus such as a Lightbridge 2 (LB2) apparatus. An executing entity of process 402 may include a main controller of the UAV.

In some embodiments, process 402 may include controlling a color of the indicator light and/or a blinking frequency of the indicator light to indicate an execution status of the control instructions executed by the UAV.

In some embodiments, the execution status of the control instructions executed by the UAV may include a flight mode of the UAV after the UAV executes the control instructions. Further, the execution status of the control instructions executed by the UAV may include whether the UAV successfully executes the control instructions. If the UAV successfully executes the control instructions, a flight mode of the UAV after the UAV executes the control instructions may include a flight mode of the UAV after the UAV successfully executes the control instructions. If the UAV fails to execute the control instructions, a flight mode of the UAV after the UAV executes the control instructions may include a flight mode of the UAV after the UAV fails to execute the control instructions. Further, the execution status of the control instructions executed by the UAV may also include the control instructions being successfully received.

In some embodiments, controlling the color and/or the blinking frequency of the indicator light may include controlling the indicator light to emit light of a fifth color, and/or controlling the indicator light to blink at a fifth frequency. In some embodiments, flight modes of the UAV after the UAV successfully executes the control instructions may correspond to colors and/or frequencies in a one-to-one manner. For example, when the flight mode of the UAV is the A mode, the indicator light of the UAV may blink slowly in yellow. When the flight mode of the UAV is the F mode, the indicator light of the UAV may blink rapidly in yellow. When the flight mode of the UAV is the P mode, the indicator light of the UAV may continuously emit yellow light.

Similar to the situation for the camera, for the UAV, not only the indicator light of the UAV may be controlled to indicate success or failure of the UAV executing the control instructions, but also the attitude of the UAV may be controlled to indicate an execution status of the control instructions executed by the UAV, e.g. a flight mode of the UAV after the UAV executes the control instructions or whether the UAV successfully executes the control instructions. Reference can be made to descriptions for the camera, which are not repeated here.

Further, after process 402 is performed, the method may also include controlling the indicator light at the UAV to switch from indicating the execution status of the control instructions executed by the UAV to indicating the operation status of the UAV. For example, at process 402, the UAV may control an indicator light at the UAV for indicating a nose position of the UAV to indicate the execution status of the control instructions executed by the UAV; and after process 402, the indicator light may be switched to indicate the nose position of the UAV.

In some embodiments, the color and/or the blinking frequency of the indicator light at the UAV may be controlled to indicate the execution status of the control instructions executed by the UAV, where the control instructions may be configured to control the flight mode of the UAV, such that the operator can observe the UAV to determine the execution status of the control instructions executed by the UAV. Accordingly, time for the operator to observe the indicator light on a remote controller or an APP may be reduced. Distraction of the operator's attention from observing the UAV caused by a need for the operator to constantly observe the indicator light on the remote controller or the APP may be suppressed. A potential safety hazard for the UAV operation may be suppressed.
